| 摘 要： | 针对开发建设项目水土流失预测方法现状,在充分考虑建设项目扰动堆积体物质特殊性的前提下,引入了土壤可侵蚀面的概念,并对开发建设项目的可侵蚀面进行分类。在此基础上,应用组合数学原理,利用侵蚀产沙函数和可侵蚀面的模块组合,建立基于可侵蚀面类型的开发建设项目水土流失预测模型。该模型的最大特点就是精度高、计算方便,所用参数容易获得,所得结果符合客观实际。

| Abstract: | Soil erosion surfaceis introduced and classified to help study prediction methods of soil and water loss in development and construction projects with consideration of construction projects'disturbance on particularities of the accumulation body.A prediction model of soil and water loss is established based on the type of erosion surface by combining the function of erosion sediment yielding and the module of erosion surface.This model is accurate,easy to calculate with accessible parameters and objective a... |
